Documents obtained by The Baltimore Sun say that about a dozen items, including a condom wrapper and fingernail clippings, were tested and none of them were positive for Syed. The only DNA investigators found belonged to Lee herself as well as an unidentified woman.

Maryland Attorney General's Office spokeswoman Raquel Coombs says the lack of DNA doesn't exonerate Syed, who was convicted in 2000 of strangling Lee and burying her in a Baltimore park.
